Environmental impact
NDD Print 360 presents indicators of the environmental impact resulting from all the pages printed in a given period, to help raise awareness among users of the environment. It is possible to have relevant information on estimates of this impact. The database uses international and consolidated references to present the information.
The indicators
The calculations used by NDD Print 360 are listed below. These values may vary according to the context of production and the paper used, but they serve as a reference, based on the following sources, of the impact resulting from the prints made:
Water: 0.401 liters of water per printed page
Energy: 0.02901 kilowatt-hours per printed page
CO²: 0.0000404191 tons of carbon dioxide equivalent per printed page
Source: Environmental impact estimates were calculated using the Environmental Paper Network with Paper Calculator version 4.0
Trees: 8.333 pages produced per tree

It is possible to have a general view of the environmental impact, but to do so your user must be an administrator or account manager, in the latter case, only data from users under your management will be presented:
General environmental impact information
The values shown are estimates and may vary according to different scientific and consumer aspects, such as user habits, the references considered, the calculation method, the type of paper, the origin and more
Knowing the reference values
Water: The water baseline measures the amount of cooling process water consumed or degraded during the entire life cycle of paper production. For the estimate, a standard type of paper used in office and/or commercial printing is considered. The reference values identified are then converted into liters of water/printed page.
Energy: This indicator considers all the energy required during the life cycle of paper production, including, for example, renewable and non-renewable energies and the use of cellulose and paper industry resources such as black liquor. The reference values identified are then converted to kilowatt-hours per printed page.
CO²: This value considers the emission of carbon dioxide (or CO2), resulting from the burning of fossil fuels, methane, decomposition of paper in landfills and other short-lived climate pollutants, such as black carbon and organic carbon, which contribute to climate change in the Earth's atmosphere. The calculation basis can also include the loss of forest carbon storage from logged forests
More on greenhouse gases
The so-called CO2e, or CO2 equivalent, is a metric used to compare the emissions of various greenhouse gases, based on the global warming potential of each one, defined in decision 2/COP 3, or subsequently revised in accordance with article 5. Carbon dioxide equivalent is the result of multiplying the tons of greenhouse gases emitted by their global warming potential
For example, the global warming potential of methane gas is 21 times greater than the potential of carbon dioxide (CO2). So, we say that the CO2 equivalent of methane is equal to 21.

Trees: The estimate considers that, on average, a tree produces 16.67 reams of A4 paper, each with 500 pages, resulting in 8,333 pages of paper per tree. While some variables can have an impact on the exact amount of paper produced, such as the type of tree and its size, different studies, in addition to the source cited, consider the same value, reinforcing the accuracy of the estimate.
More about the sources
The source of the estimates presented is supported by the Environmental Paper Network, an international coalition of more than 140 non-profit organizations, and is widely known as one of the most reliable and transparent sources of environmental impact estimates.
The scientific basis behind the calculations, as well as additional information about the network, are the responsibility of the authors and can be found in the official links presented throughout the document
